Tiny 1mm creatures free swimming after lights out

[danielankeny]

Hi all. I doubt i can get a pic or video but only after lights out, i have many free, eratically swimming creatures that are about 1 mm size, brownish orange in color. The tank is about 8 months old and doing well. Anyone seen something like this or have a clue what they could be?

maybe amphipods/copepods?

Could be tropical mysis shrimp or larva from something spawning in your tank.

likely a good sign of a healthy reef

Still pictures don’t show all the little things that are moving around but I am always happy when I see them. I know that my fish like them also. Generally a good thing although occasionally something may sneak in that I don’t want.
